As you go higher up the ladder, the possibilities are endless in terms of customization. You can choose wood, scale, and a host of other design options. And there are parlor sized options from builders like Larrivee and others.

From small shop builders there is the Collings baby and Santa Cruz firefly. As for individual luthiers Laurent Brondel makes a D-5 which is an early ditson inspired design the size of a Martin 3. Michi Matsuda also does a modified mini parlor guitar. I am sure there are a lot of other luthiers making parlor guitars but those are the two that immediately come to mind.

I think I have it!!!
I'm reintroducing my "original" Voyage Air shape (both folding and not) not to be confused with Voyage Air B size this one was only used on the prototype. 24" scale length, 13.25 lower bout, 17.25 body length... as far as price goes, it's only $6500.00 but the list of options could easily add another zero to that...
